移动荷载作用下的土质路基板式轨道动力响应分析

在高速行驶的条件下,根据车辆与轨道路基相互作用的机理以及影响因素,分析研究列车作用于轨道与路基上力的大小,通过建立板式轨道土质路基有限元分析模型,对路基所受到的动应力、动位移进行分析,研究轨道路基结构各组成部分参数的合理配置。

Dynamic response analysis of slab track on the soil subgrade by moving load

Under high-speed terms of going,this text main research is the mechanism of interacting with the road bed of track according to the vehicle and influence factor,analyse and research the size that the train vehicle acts on the strength on track and road bed,cut the road bed of track and not have finite element which cut the road bed of track to analyze models through setting up,what is it is analyzed that the road bed received moves the stress,moves displacement,analyse and research and cut/have rational disposition problem which cuts every component of road bed structure of the track.
